ASSEMBLY PLATE AND DIE-HOLDING CLAMP.

Serial No. 63,356.

Fig. 11 is a view corresponding to Fig. 10, but further showing plaster of Paris, poured on the paraffin and completely filling the dies and holding the frame;

Fig. 12 is a sectional view of the dies mounted in the holding frame with the paraflin removed to expose the cutting edges of the, dies;

Fig. 13 is a face view of the parts shown as a copy sheet on which is printed a figure 16 representing St. Patrick, to be used as a pattern while forming a die to out such printed figures from sheets of paper stock, to be used as place cards, one of which is shown on Fig. 7 Also cut from the paper stock with the figure 16 is a base 17 having tapered end extensions 18 which, when turned backward, will support said figure in an upright position but slightly backwardly inclined, due to the tapered under edges of said end-extensions. To make these end extensions 18 bend easily at the proper places, the paper stock is scored at 18.

lVhile forming a die for cutting the figure 16, base 17 end extensions 18 and producing the scoringlines 18, the copy sheet is placed'on a fiat assembly plate 19, preferand to'prevent solder from sticking thereto while soldering the ends of the die sections.

This assembly plate 19 has at its back a centrally located headed stud 19 removably journaled in the bifurcated upper end of a supporting bracket 20 securedto a table or other support 00. The mounting of the assembly plate 19 is such as to hold the same oblique in a vertical plane with freedom to 9 rotate in its own plane, fora purpose that will presently appear. Said assembly plate '19 has drilled and tapped therein a plurality of longitudinal and transverse'rows of holes 20. i

The completed die for cutting the figure is indicated as an entirety by the numeral and comprises a plurality of sections 01 eel cutting rule, one of the longitudinal of which is sharp, bent to the contour the figure 16, base 17, and end extensions 18, and which sections are rigidly connected by solder. As shown, the die 22 includes two horizontal base sections havingcoir verging end extensions 24: connected their abutting ends by solder a pair of upright side sections connected at their abutting upper ends by solder 27 and having; their laterally spaced lower ends secured to the upper base sections 23 by solder 28: pair or" incl d8 upright sections 29 having their abutting upper ends connected by soil-- der an) and their laterally spaced lower ends secured to the upper base section by solder 31; and pair of upright inside sections 32 having their abut-ting upper ends connected. by solder and their laterally spaced lower ends secured to the upper base section 23 by solder The base sections 23 follow the contour oi the base 17, and their extensions 24; tollow the contours of the end extensions 18. vThe side sections 26 follow the irregular outer contour of the figure 16, and the sections 29 and follow certain contours of the figure 16 to make inside cuts. A relatively narrow crosstie-bar 35 has one '01 its ends soldered to one of the sections 29 and its other end soldered to the adjacent section 26. to hold the sections 29 in their similar cross-tiebar 36 has sections A is soldered to one ot. the secone of its end -.d its other end soldered to the acqacent section 26 to hold the sections 32 in their proper upright position in respect to the sections 26.

To prevent the upper base section 23 from cutting'the figure 16 from the base 17 said section is not between the sections 26 and the adjacent sections and and between the adjacent sections 29 and 32. as indicated at 37. Scoring blades 38, for producing the scoring lines 18, extend between the base sections 2. at the ends thereoi and are rigidly secured thereto by solder 39. These scoring blades are formed from steel cutting; rule and have their sharp edges spaced ab vethe sharp edefes oi the sectiong'23. so as to simply score not cutthe paper stock.

As each section of the die 22 is formed it is placed on urelfithat ed at its cutting edge representsand held in position by one or more clam as 40. Each clamp 10.

comprises a horizontal finger-like body and long thumb screw ll. Said body has at its rear end, wide transverse supporting foot l2 and at. its trontend, .a gooscn'ecltil wif-h a transverse notch e ite receive andhold the upper edge portion of a die section. The

the respective portion. of the fig-- L edge resting on said-sheet. temporarily held in this positionby gmeans A collar 46 on each thumb screw l1, inward off the body of the clamp 40, holds said body and thumb screw assembled when the clamp is removed from the assemblyplate 19. In case the copy sheet 15 extends over the hole 21 in which the thumb screw ll is'to be screwed, a hole i7 may be cut in the copy sheet 15 to expose said hole.

After all of the sections of the die 22 are completed, assembledon the copy sheet- 15 and held in position by means of the clamps I 4:0 the assembly plate is mounted on the supporting bracket '20 and the ends of the die sections are connected. by solder to each other or other parts of the die sections.- By mounting the assembly plate 1-9 on the supporting bracket 20, same is held thereby in a convenient position and may be rotated to bring the various parts of the die into con venient positions for soldering. After the soldering; of the die sections is completed the clamps 40 are removed from the assembly plate 19 to release the completed die 26, as shown in Fig. 4.

It is, of course, understood that in making a die, one or a plurality of sections of cutting rule may be used and the oints made at any convenient place and connected by solder or otherwise. Any suitable tool or tools may be employed to bend the die sections to the exact shape of the figure or object they are intended to cut. In forming the die sections,

the cutting edges of-the rule must always be turned toward the copy sheet. die is completely finished, the scoring blades 38 are soldered in position with theirsharp, edges spaced the proper distance above the cutting edge of the die 22.

It maybe here stated that at the time the Before the copy sheet 15 is printed, the entire number] ot'sheets for the respective job are printed. Two or more figures or ob ects may be printed on a single sheet to prevent waste. and to facilitate the cutting of the figures from the paper. stock, and said figures may represent a single job or a plurality of jobs. In addition to the figure '16. there is also printed on thesheet therewith a heart-shaped figure 48.

In Fig. *8 is shown a sheet of paper stock selected from the job on which are prin ed the :figures'lG and 18 and which sheet will hereinafter be referred to as a positioning sheet 49. r

The positioning sheet 49 is 'placed on a wooden mounting board 50 and thedie 22 is positioned joverthe figure .16 with its .cuttin-r @1116 die i of a pin 51 having just under its head a sleeve 52 of cork, rubber, or other resilient material. This pin 51 is pressed through the positioning sheet 49 and into the mounting board 50 with the lower end of its sleeve 52 engaging the upper edge portion of the die 22 under compression to hold said die where positioned. More than one pin 51 may be used, if necessary, to properly hold the die 22 in position. A. die 53 for the figure 48 is positioned on said figure and held by one of the pins 51.

Placed on the positioning sheet 49 around the dies 22 and 53 is a shallowrectangular depth frame 5% made up of four loose slugs or bars. Resting on this frame 54 is a correspondingly formed'holding frame 55 comprising rigidly connected slugs or bars set edgewise with their upper edges in the same plane as the upper edge of the die 22. Melted paraffin 56 is poured into the depth frame to the upper surface thereof and into the bodies of the dies 22 and 53 to a corresponding depth and allowed to set. as shown in 10. After the paraiiin 56 has set, the pins 51 are removed as they are not necessary for the reason that the paraffin will properly hold the dies.

Plaster of Paris 57, in plastic form, is-

then poured on the paraffin Within the holding frame 55 and bodies of the dies 22 and 53, so that said frame and dies are completely filled. While the plaster of Paris 57 is setting, a heating process takes place and the action thereof on the paraffin loosens and draws the same away from the contact ingsurfaces of the dies 22 and 53 and the depth frame 54; so that the paraffin 56 may be easily lifted from the dies when they are removed from the depth frame 54: to expose their cutting edges, as shown in Fig. 12. 7

Obviously, the bodies of plaster of Paris in the dies and surrounding the same rigidly hold said dies and secure the same to the holding frame 55. Pieces of cork 58 are then glued to the plaster of Paris 57 within the dies 22 and 53. The purpose of these cork pieces 58 is to press the paper stock from the dies after the cutting action has taken place. The holding frame 55 is then mounted in a press, not shown, to cut the figures from the printed paper stock as the same is fed to the press. After a job is completed, the plaster of Paris in the holding frame 50 may be broken up to release the individual dies with their bodies .of cement from said frame so that they may be stored away for further use and may be again mounted in a holding frame either alone or with other figures.

In place of the paraffin 56, a resilient substance, for instance such as used in making composition rollers, may be substituted therefor and left in the dies to take the place of the cork 58 for projecting the figures as they are cut by the dies. .The dies are so designed as to cut the figures from the paper stock but not remove the same so that said figures are removed from the press with the waste material. In place of the cork 58,

rubber or other resilient material may be used and the words plaster of Paris are herein used in a broad sense to cover any kind of cement for securing the dies in posi tion. The words cutting rule are also used in a broad sense to cover any suitable material from which the dies may be formed.

The above described apparatus has. in actual commercial usage, proven highly efficient for the purpose had in view. Dies formed in accordance with our invention will cut figures or designs to their exact shape and may be made to out very intricate designs and. at the same time, leave the outlines thereof very sharp.

What we claim is:

1. The combination with an assembly plate having a multiplicity of-vertic-ally and horizontally spaced rows of holes, of a rigid clamping finger having an intermediate longitudinal slot, an adjustable anchoring member extending through said slot and adapted to be secured'in any one of said holes, said clamping finger havingat one end a supporting foot and at its other end a notched gooseneck for engagement with a piece of work.

2. The combination with amounting board for a die, of means for temporarily holding the die on the mounting board, and a tem porary depth frame and a holding frame adapted to be supported on the mounting board around the. die.

3. The structure defined in claim 2 in which the holding frame is removably supported on the depth frame.

4. The combination with a mounting board for holding a figure or design and a die for cutting the same, of means for temporarily holding the die over the figure or design,

and a temporary depth frame and a holding frame adapted to be supported on the mountmg board around the die.

5. The combination with a mounting.

which the means for securing the die in the frame is a cement that maybe crushed to detach the die from the frame.

. 7. The combination with a mounting board for holding a sheet having a plurality of figures or designs and dies for cutting the same of means for temporarily holding dies over the respective figures or designs a frame adapted to be placed around the dies, and means for securing the dies to each other and in the frame.

8. The structure defined in claim 7 in which the means for securing the dies to each other and in the frame is a cement that may be crushed to detach the dies from the frame and from each other. 7 10 In testimony whereof We aifix our signatures.
